I messed up. How do I fix a mistake on my ballot?
First, don’t panic.
People make mistakes on ballots, and they also find good ways to correct them. The job of county elections officials — once they’ve verified your signature — is to make sure your ballot can be read correctly. If that means that your corrections on your ballot have resulted in readability issues, officials working in teams of two will actually remake it for you according to the intent you’ve signaled with your corrections.
The main thing to know is that there’s no one-size-fits-all approach to fixing a mistake on your ballot in California — how a voter corrects a goof is up to the county, and those instructions vary from place to place.
Your own county’s advice for how to fix a mistake on your ballot is almost certainly printed on your ballot, so check there first. But here’s what each county’s registrar told KQED in 2024 about fixing a mistake, so scroll down to find your county or use the quick links below. If they sent us a visual guide, we’ve included that, too.
And if you have a specific question about your ballot that isn’t answered here, you can always contact your local county elections office for advice and instructions.
Alameda
Alameda County’s ballot instructs voters to request a fresh ballot if they make a mistake, rather than try to correct it.
Jump straight to how you can get a new ballot. You can also call the Alameda County Registrar of Voters at 510-267-8683 or 800-345-VOTE(8683) with questions about your individual ballot.
Contra Costa
If you make a mistake, Contra Costa County Registrar Kristin Connelly told KQED that “A simple X through the oval of the incorrect choice and a filled-in oval on their correct choice is enough.”
“[A]s long as we can determine what the voter’s intent is, we can make sure we count their vote correctly,” Connelly said. But if you’re still worried about your vote, you can always ask for a replacement ballot, to either mail back or use to vote in person.
“It’s totally up to the voter and what makes them comfortable and secure that their vote will be counted,” she said.
Napa
John Tuteur, Napa County Registrar of Voters, said that if someone makes a mistake on their ballot, like marking Yes when they meant to mark No, “they should circle the correct choice and draw an arrow to it.”
The county’s vote-counting machines — technically known as “optical scanner ballot tabulators” — will automatically flag and forward any ballot that shows an “overvote” like this (i.e., when a race has more answers than is permitted) to staff who are trained to adjudicate these things, and work out what that voter intended with their correction.
This process is all documented, Tuteur said, so elections staff always know which adjudicator reviewed which ballot and what they decided.
Santa Clara
Steve Goltiao, associate communications officer with Santa Clara County’s Registrar of Voters, said you can “correct it by crossing out the wrong choice and filling out the correct oval as shown in the picture” below. You should not sign or initial the correction, Goltiao said.
You can also request a replacement ballot by calling 408-299-VOTE (8683) or toll-free 866-430-VOTE(8683). “Voters may also use the Remote Accessible Vote by Mail System (RAVBM) to download a copy of the ballot that can be printed and returned by mail,” Goltiao said. Read more information for Santa Clara voters about marking and returning ballots.
San Francisco
“[V]oters can request replacement ballots if they make a mistake marking a selection,” San Francisco Department of Elections Director John Arntz told KQED. You can request a new ballot in person at your polling place and, from the San Francisco elections office at City Hall, and by calling or emailing the Department of Election (scroll to the bottom of this link for contact details.) You can also use their Voter Portal online to request a replacement ballot.
But if a voter doesn’t want to — or can’t — request a replacement ballot, Arntz said, “We tell them they can also cross out the incorrect selection, fill in the correct oval, and note on the card they made a mistake.” The reason this is OK, Artnz said, is because the vote-counting machines will recognize and flag any ballot that contains more than the allowed number of votes for a particular race. The ballot is then “moved to manual review or adjudication,” and elections staffers will personally look at the ballot to work out what the voter meant.
“When voters indicate they made a mistake, our personnel will remedy the overvote to reflect the voters’ intent, and the card is then tabulated,” Artnz said.
San Mateo
Mark Church, San Mateo County’s assessor-county clerk-recorder and chief elections officer told KQED that “any additional markings a voter makes including an ‘X’ through a selection choice on the ballot” will cause the ballot to get flagged and placed in a “challenged” status. Then your ballot is sent to one of the county’s adjudication stations, where a staffer will determine how you meant to vote with your markings.
“Thus, it is preferred that a voter request a replacement ballot if they make a mistake in marking their ballot,” Church said — which you can do in person by visiting one of the county’s 49 Vote Centers or calling the Elections Office at 650-312-5222.
Solano
“[L]ike lots of things, it kind of depends on the case and how close to election day it is,” Solano County Assistant Registrar of Voters John Gardner told KQED. But as a general rule, he encourages Solano voters to “call our office and talk to staff so we can go through the options” or email them.
Your options, which an elections staffer can go over with you, include writing notes on your ballot to make your intention clear (“i.e., add arrows to the correct choice and write ‘I want this one’ next to it or something like that,” Gardner said, so the human reviewing your ballot can understand it). You also will have ways to receive a new ballot, including requesting a totally fresh one, using a sample ballot or even printing a new one yourself from a secure site.
“[W]e do have a lot of options for voters, but it’s really best for them to get in touch with us to help them understand all the possibilities based on their situation and needs,” Gardner said.
Sonoma
“Voters should put an X over the incorrect choice and mark the correct one,” said Deva Proto, clerk-recorder-assessor and registrar of voters of Sonoma County. “Voters can also request a replacement ballot, if they feel more comfortable with that, or go to any in-person location to vote or get a replacement ballot.”
And remember, there’s always this option …
Marin
Marin County voters “can X out the mistake and mark the correct vote,” Lynda Roberts, registrar of voters, told KQED. “As long as we can see their intent, we can count the vote.”
Marin voters “should not initial or write their name next to the change, however, since ballots are to remain anonymous,” Roberts said.
What if I just want a new ballot?
If you’ve made a big mistake on your ballot — too big to fix — your best plan of action may be to focus on getting a new one. You can:
- Call your county elections office and ask them to cancel that ballot and issue a new one to you
- Go to your county elections office with your spoiled ballot during business hours and vote right there at the counter
- Take advantage of the early voting options available in many counties
- Go to a voting site on Election Day, turn in your spoiled ballot there and get a new ballot
You can also do this if you’ve accidentally damaged your ballot in some way (coffee spills happen.)
What if I have problems with my signature?
When you’re done filling out your ballot, you must sign the envelope (not the ballot itself, as they are meant to stay anonymous.)
But a few big mistakes people can make with their signatures are:
- Forgetting to sign their ballot envelope
- Accidentally signing the wrong ballot envelope in their household (i.e., mixing up your ballot with your partner’s or roommate’s ballot) or
- Making a signature that doesn’t match the signature they made when they registered to vote.
Why wouldn’t your signature match the one on file? If you registered to vote at a young age, maybe your signature has changed over time. Or perhaps you registered to vote at the DMV and provided your signature on a screen with a stylus, which doesn’t quite replicate how you’d make your signature with a pen on paper.
If you registered this way, one simple way to avoid any signature problems is to take a quick glance at the signature that’s on your driver’s license or state ID — because that’s usually the one you want your ballot signature to match.
Even if you didn’t register at the DMV, that signature on your most recent license or state ID is still very likely the one to emulate. That’s because when you register to vote online, your county elections office electronically requests a copy of the signature the DMV currently has for you, and this information is regularly updated.
To further set your mind at rest, know that California isn’t an “exact match” state and doesn’t demand voters’ signatures 100% replicate the signature that’s on file.
What if I just don’t know my ‘correct’ signature I’m registered to vote with?
If you’re really worried about the signature on your envelope not matching the signature you’re registered to vote with, there are two good solutions.
One: If it’s on or before Oct. 20, you can re-register to vote with your current signature to be sure that the state now has your most recent one on file. If you are re-registering after Oct. 20, you’d need to complete the same-day voter registration process (also known as “conditional voting”) and request your ballot in person at your county elections office or polling location.
Two: In 2021, Kim Alexander, president of the nonpartisan California Voter Foundation, told us there’s another solution if you’re worried about your signature: Go vote in person, if you’re able.
That’s because the signature only goes on your ballot’s envelope — and if you’re voting in person, that ballot goes straight into the ballot box without needing an envelope at all.
“So if you want that satisfaction of seeing your ballot drop in the box and know that it’s not going to get held up because of some signature issue, you can go and vote in person,” Alexander said.
Thanks, KQED: I already mailed my ballot, but now I’m paranoid about my signature. What if I messed it up?
Rest assured: There’s a whole system in place to help you correct your mistake.
If your county’s election office detects a signature mismatch on your ballot, they’ll reach out to you via mail to verify and work with you to correct it so that your ballot can be counted after all. It’s called “curing” a ballot.
This system is also applied when it looks like a member of a voter’s family might have signed their ballot instead of the voter. This happens a surprising amount when one household has several voters who all receive a ballot in the mail.
One way to get peace of mind: Sign up to track your ballot, and you’ll find out about any issues with your ballot or your signature quickly.
I think I put the wrong date on my envelope
First off, that date should be the date you signed your envelope — not your date of birth.
But if you’re worried you messed up the date, don’t worry. Elections officials said that the date they’re really looking for is the date that the ballot is postmarked to make sure it was submitted on time.
Election officials will only truly scrutinize the date you’ve written if they receive your ballot after Election Day.
And if you haven’t mailed your envelope yet, it’s an easy fix: Just clearly cross out the incorrect date on the envelope and write in the correct one above it.
What if I use assistive technology to complete forms?
Getting physical assistance with filling out your ballot from someone you trust is always fine, whether you’re voting at home or at a voting site. You just need to make sure your signature is your own and matches the one you’re registered to vote with.
Disabled voters can also choose to use the Remote Accessible Vote-by-Mail system to vote privately and independently at home, using their usual assistive device on their home computer to fill out the ballot on their screen and then print and mail it.
Every voting location in California is also equipped with an accessible voting unit. Here, voters who are blind, have low vision or have a disability that affects their dexterity can use an assistive device of their choice to vote privately and independently.
How can I make sure my mail-in ballot gets there on time?
Remember, one of the main reasons ballots are disqualified is because voters mail them too late — either after mailboxes have been collected on Election Day or after Election Day itself.
To be counted in this election, your ballot must be postmarked on Nov. 4 at the latest. Your ballot has seven days — until Nov. 11 — to reach your county elections office.
So in this election, it’s more important than ever to make sure you have a plan to vote on time — and if you’re not voting in person, that means making sure your ballot is in a USPS mailbox, a secure voting drop box, at a polling location or your county elections office by the time polls close on Nov. 4.
If you’re choosing to mail your ballot via USPS, keep in mind that the Postal Service must postmark your ballot envelope by the end of Election Day for your vote to count — and the last collection at many mailboxes is 5 p.m. So if it’s getting late on Nov. 4, consider using a county drop box instead of a USPS mailbox.
A few other common ballot mistakes to watch out for …
Make sure you use a black or blue pen: It reads better, and it doesn’t slow workers down when they have to check to see what voter intent was. (Don’t use a felt-tip or a Sharpie that bleeds through the paper and marks other pages on your ballot.)
Don’t mail an empty envelope: It does happen. Keeping your envelope and your ballot together in your home might be a helpful way of avoiding this problem. And, of course, when you’re ready to mail your ballot, make sure it’s actually inside the envelope before you seal it.
Don’t bother with a stamp: Your ballot envelope is postage-paid. You don’t need it.
And again, make sure you’re filling out the ballot — and signing the envelope — with your name on it: It’s common to see roommates or family members accidentally mix up their ballot materials on the kitchen counter. So make sure you’re filling out the ballot and signing the envelope that bears your name.
And remember, you don’t have to vote by mail
Since 2020, every registered voter in California now receives a mail-in ballot by default without having to request it as in previous years. But voting by mail is still one option open to you.
You can still absolutely vote in person, either at an early voting location before or on Election Day. If you live in Alameda, Marin, Napa, San Mateo, Santa Clara or Sonoma, Vote Centers in your county open on Oct. 25 (or earlier in some cases), where you can go in person. Assigned voting locations will open a little later in San Francisco, Contra Costa or Solano for those counties’ voters, although some early voting sites will be available in those counties — for example, at your county elections office.
See where early voting will open in your county.
